WEB SDR MORSE DECODER ANDROID

Maybe a simple graphical indication of the CW detection (slice) level could be provided to help fine tune reception. I suspect that some software tweaking of the level into the decoder may be required to optimise the extension. Reducing the AGC delay to 50ms also helps with fading signals. A lot depends upon the noise floor of the KiWi in use. Wideband display and decoding shown below requires a wideband SDR. Too low a threshold produces too much background noise and generates garbage like strings of EEEEEEEE and too high a level results in only decodes from very strong signals. a fast waterfall display, with a resolution sufficient for reading Morse Code dots and. I've been experimenting with the KiWi extension and have found that selecting a narrow <50Hz CW bandwidth and then adjusting the AGC threshold for best results seems to be quite effective. In contrast to other web-controlled receivers, this receiver can be tuned by multiple users simultaneously, thanks to the use of Software-Defined Radio. Tuning is different from the normal WebSDR: do not drag the yellow filter curve, but the waterfall.

It should work using Safari on iOS devices Firefox or Chrome on Android devices and Edge on devices running Windows 10. I can decode most morse signals reasonably well if they register >S4 on the signal strength meter, I suspect that CwGet performs slightly better because it has more user adjustments to play with. On this page you can listen to and control a short-wave receiver located at the amateur radio club ETGD at the University of Twente. This is an experimental version of the University of Twentes WebSDR receiver for smartphones and tablets. I'm not quite sure what level of performance folks were expecting for 'free' ?
